Measure distance behind walls

If you want to go through walls, how did you intend to define the endpoint for your distance measurement? Are you thinking between, e.g., a transmitter and receiver that might be on opposite sides of a wall?

Yes lets say I would like to mwasure the distance between the corners of my house with no line of sight. Only with two devices at either end.

Is it possible

Thanks George

Possibly, with DGPS. It depends on how clear a view of the sky you have.

Theoretically radar at the right frequencies could do what you want. You might want to look at Ground Penetrating Radar, which does something similar and is in use in the 'real world'. If you want to do it without a big (military, corporate, research...) budget I think you're out of luck.

A dgps unit with distance travelled between waypoints.

Yes, for very large amounts of money.

Why not just pick a third point, visible from both A and B, call it C, and just trig it out?

C / \\ / \\ / \\ / \\ / _____ \\ / [ ] \\ A [HOUSE] B [_____]

Measure the distances AC and AB, and the angle ACB, and it should be just arithmetic from there.

Good Luck! Rich
